assign it to me?

> Key: FLINK-35129
> URL: https://issues.apache.org/jira/browse/FLINK-35129
> Project: Flink
> Issue Type: Improvement
> Components: Flink CDC
> Reporter: Hongshun Wang
> Priority: Major
>
> After entering the Stream phase, the offset consumed by the global slot is
> committed upon the completion of each checkpoint, preventing log files from
> being unable to be recycled continuously, which could lead to insufficient
> disk space.
> However, the job can only restart from the latest checkpoint or savepoint. if
> restored from an earlier state, WAL may already have been recycled.
>
> The way to solve it is to commit the offset after every multiple checkpoint
> cycles. The number of checkpoint cycles is determine by connector option, and
> the default value is 3.
